yes it does, it is in my bedroom, my main tank is virtually silent appart from the air bubbles from the airstones. both tanks use Tetra tec dual outlet APS 300's they them selves are super quiet pumps.
This tank if i do not have the bubble wall on is almost silent aswell. the eheim powerhead is inaudiable and like i said produces lots of flow and bubbles to oxygenate the water that it why i think it is so good

.
My main tank runs on a eheim 2224 professional that is also silent! this is what i will be buing tomorow for this tank...
Both tanks are next to eacxh other at the end of my bedroom, they are heard but only quietly and i have no problem (or my girlfriend) of getting to sleep). the sound of trickling water is actually quite theraputic! they dont interupt listening to the tv or radio either.
these are the onl two tanks of mine at the mo, my dad has a discus/ community tank downstairs and a small community tank in the kitchen.
I want to add another zeb tank and put it in the lounge but dont think ill be allowed. cant wait till i get my own place and can build a fish house especially for the zebs! may also get some microgeophagus ramerizi and breed them again too... (but thats not going to be anytime soon!

)
